Injectors/gears/dic???

[Jacob_Royer]

Ok i have a situation here.. I am at a point where everyone says i need 42lb injectors and 76mm maf.. But I don't have enough $ saved up for it before the shootout.. But I do have enough to get eaither a DIC or Gears (know of a deal on eaither) What should i do?? I'm leaning twords gears(3.73's) but.... If i got a DIC than more blower OD would be sweet but then i wouldn't have enough fuel.....argh.!

[THE BIRDMAN]

A double ic is gonna run you about 4 bills or more.You can get injectors and maf for about the same.By the time you buy a set of gears and get them installed you'll probably be over 400 for them also.So if you are out of injector now then I would go for the injectors and maf.Cause a lean blown motor is not a happy one!!Do you have an i/c fan yet?If not you could pic up one for 60 bucks or so.Gears are always a nice addition but if you're maxing out you're injectors now then I'd buy them first j/m/h/o.

Already have a IC fan.. the gears i'd be buying the whole diff already setup.. For the price i could get the DIC and the gears for i could probably swing both before the shootout but the maf,injectors,tune and 255lph pump no way.. I'm thinking those 4 things i need to have and do all at once.. I'm only running a 5% pulley right now and am keeping it below 5k rpm so I think i should be safe 10PSI boost is all i've got.. How hard is it to swap the rear pumpkin out?

[XR7 Dave]

Put a fan on the stock IC, yank the AC condensor for now, get the 42's and get the car tuned. Once the car is tuned with the 42's then you can add stuff and the car will respond to it. If you add the other stuff first then you will be out of fuel and battling issues for the next who knows how long.

Running the car at the Shootout without enough fuel will be a dissapointment and could be hazardous to the motor's health.

It's easy it'll only take you about an hour to do it.

I totaly understand that i need more fuel but there is no way in hell i'll be able to get all the parts I need and install them and get it tuned before the shootout..


injectors and maf $300/$400
255lph Fuel Pump $100
Tune $250/400 with dyno time etc.

Time to get all the shipped and installed???? Time to make a trip to get it tuned?? Its not that I don't plan to get the injectors & Maf its the fact that I can get the gears and DIC localy at a really really good deal. If I could throw injectors and maf at it and be able to get by without a bigger fuel pump and a tune for a while i'd do it.. Fuel pump is going to be a pita to change by myself and If I get the injectors and maf it will be awhile before I have enough $ to get a tune.. a DIC with the fan I already have I'd imagine would make a good diffrence in this crappy hot humid weather we have right now (it was a 100deg yesterday!).. What if i stick my stock blower pulley back on? hell i'll probably only make 7/8psi with it! how could i posibly not have enough fuel for that? For the most part i've been keeping this engine under 5000rpm and only had it past it once.. If i had 3.73's I'd pickup alot of low-end power i've lost (i'm assuming) Keeping it under 5000rpm am i still running dangerously lean? I'm assuming the computer is pulling timming like crazy right now because of the outside temprature? I can't tell any diffrence with the octane plug out right now if that tells you anything because i've ran it both ways... I'm not trying to argue with you guys because you know alot more about this than I do so tell me if im being stupid about it and i'll listen... Its just the fact that I can get 2 things on my list that are easy to install for the price i'd pay for maf and injectors that I can't use without a tune and a fuel pump upgrade..

Just leave it like it is until after the Shootout.

If your really concerned about the fuel, you could install a larger fuel pump and an adjustable regulator as a temporary measure.

David

[Jacob_Royer]

What just crank up the pressure to the stock injectors?

[92sclikenew]

or you can buy the parts you want and wait to install it as a package.. :eek::rolleyes:;)

and then do as dave said leave it the way it is for the shootout..

i think u'd be fine with just the right sample tube in the MAF for the injectors. then do the fuel pump.

and u can hook up an air/fuel gauge, which i know a narrowband sensor isnt gonna tell an exact number, but it will at least let u know if you're really lean or not.

[Jacob_Royer]

Wouldn't 3.73's be a nice upgrade anyway? its not going to make it run any leaner or richer for that matter?? I'm just trying to squeeze some performance out of it before the shootout without doing any dammage..

So with the correct sample tube i should be able to get by until i tune it and get a bigger pump? as i said before as hot as its been i'm running way retarded on the timming..

does your car still got the a/c in it???

i takin my out like week ago, and ever since it runs like 1/2 the temp on the stock gauge.. and dosnt go over the r when getting on it.. so it helped alot when it was going to the o norm driving.. and then m and maybe a bit higher in hard driving..

Yes, 3.73s would be a great mod. I thought you only had $400, so I didn't mention them.

I still have the AC in my car and plan to keep it! everything in my car still works and the interior is mint exterior mint other than some rock chips in the hood.. I have already done the low speed fan mod and i run between n and o all the time... I can get the whole diff already setup for less than $400 is why im thinking of doing it...

That's a very good price and installing it isn't too difficult. With two people and the right tools you can have it swapped in a few hours. Biggest pain is removing/reinstalling the exhaust.

Do the gears. Best two mods I did for driveability was the 3.73 gears and the lentec valve body. They did more for how the car drove than any other things I have done

[Jacob_Royer]

What all is involved with swapping the diff? any special tools?

i have always said the same and then did it anyway:rolleyes::rolleyes:

the reason is once you start moding your gonna start to lose you stock look and ontop of that my fan dont come on till i start beating on the car or unless its like 90* out side and im sitting at a red light.. but with out my a/c all in and stuff im not even hitting the n of norm unless its really hot outside..

im waiting on my 3:73's should be here by monday.. i hope. lol cant wait.. payed $250 shipped in the rear end fully rebuilt with about 3-5 pass's on them and about 800-1000miles..

[Jacob_Royer]

Would a cheap AF guage be a good investment at this point to see what the hell is going on?

if u've got 200-300 u can get a wideband from jegs. sensor, gauge, and all.

a cheap a/f gauge would be ok. im using mine as sort of a warning light right now. it seems to be workin fine.

Come to the shoot out as is. Best bang for my buck was double intercooler, fan and getting rid of the air. Almost 1 second. 3:73 gears i dont really remember but with the drag radials my 60 ft. went way down. If you go with injectors use 60s. Once you start to really mod the motor you will run out of 42s quick. Tim

If you pull the AC condensor now, you can install a smaller parallel flow condensor later. You can get 12x20" PF condensor for about $90 from Arizona AC kits. It will open the hole in front of the stock IC and leave the bottom 7" or so of the RAD exposed to the airstream. Easily mounts with included brackets right to the underside of the RAD support. There's also a company online that will make custom barrier hoses on the cheap. You'll have all winter to get the condensor and install it. Cooling the IC and RAD down is about the only free HP we get with these beaters:). Just my $.02
